Hello, Here is a short series bringing support for Renesas RZ/N1 NAND controller. So far this driver has been tested with a not-fully-upstream device tree because clock tree is not yet described entirely, I am going to work on it really soon but I believe we don't need full clock support to get the NAND controller driver merged for now. Cheers, Miquèl Changes in v2: * Added the family-specific rzn1 compatible as suggested by Geert. Updated the bindings, the binding file name, the compatible used in the driver, the MAINTAINERS entry, etc. * Added an ARCH_RENESAS Kconfig dependency. * Changed the type (to unsigned) of a couple of variables. * Returned earlier when possible to reduce indentation. * Used platform_get_irq_optional() instead of platform_get_irq() to avoid a useless warning. * Handled probe deferral correctly. * Applied a massive s/nfc/nandc/ as suggested by Geert to avoid confusions with the near-field-communication device. * Mentioned Evatronix as original authors of the IP in the commit log and in the header. * Added an additional check on the validity of the child nodes reg property. * A couple of style fixes.
